Comparison of radon concentrations in soil gas and indoor environment of Afyonkarahisar province

It is well known that radon is the main source of natural radiation exposure to the population. Indoor radon concentrations in an area are affected by ascending radon migration following the convection of groundwater and soil gas along fractures and faults in the bedrock sediments. There are various studies showing that positive radon anomalies in the soil gas are found to coincide with the locations of houses showing the highest concentrations. Moreover, soil gas radon levels and soil permeability are important factors in determining the radon potential of an area, because high permeability enables the increased migration of radon from the soil into houses. Since radon in homes originates mainly from soil gas radon, it is of public interest to study the correlation between soil gas radon and indoor radon in different geographic locations. In the present work, a correlation study was carried in conjunction with radon concentrations in soil gas and indoor environment of Afyonkarahisar Province. The provincial center was assumed to be divided into four regions according to the rock types and tectonic structure to show also the geological structure effect on radon concentrations. The indoor radon concentrations were measured in 74 dwellings using CR-39 passive nuclear track detectors, and the radon concentrations in soil gas were determined in 243 drilled holes using AlphaGUARD detector. The correlation coefficient of 0.97 was obtained between radon concentrations in soil gas and indoor environment of Afyonkarahisar Province.Turkish Atomic Energy Authority Afyon Kocatepe University Science Research Projects Coordination Uni

Nutritional composition of black soldier fly (Hermetia illucens) reared on chicken waste meal, fruit & vegetable waste, and their mixture

Fruits and vegetables are wasted in huge amounts and nearly 30% of all produced food is never consumed which leads to many economic and environmental issues. Similarly, the poultry industry generates a huge volume of waste. This refuse is reported to have high nutritional value and could be used as ingredients in the feed industry. Black soldier flies, Hermetia illucens, are potentially capable of converting different organic wastes into protein-rich biomass and considered as a viable alternative protein source to partially substitute fish meal used in aquafeeds, thereby contributing to the sustainability of aquaculture. In this study, the effect of two different organic waste substrates and their mixture, namely chicken waste meal (C), fruit & vegetable waste (FV), and a combination (1:9) of chicken waste meal and fruit & vegetable waste (M) on the nutritional content of black soldier fly prepupae (BSFP) was investigated. Significant differences were observed in energy content and proximate composition of the substrates which significantly altered the energy content and nutritional composition of the BSFP. BSFP reared on FV were low in crude protein, crude lipid and high in crude carbohydrate compared to BSFP reared on C and M. The amino acid contents of BSFP were characterised by high levels of lysine, leucine, and valine. Significant differences were detected between BSFP groups in terms of amino acid content. The fatty acid composition of the BSFP were dominated by the saturated fatty acids (SFA) ranging between 41.8 +/- 0.10% (M) and 67.11 +/- 0.08% (C). M-fed BSFP had significantly higher SFA, monosaturated fatty acid (MUFA), and polyunsaturated fatty acid (PUFA) compositions than C- and FV-fed BSFP. M-fed BSFP had a high C18:1n9 (17.01 +/- 0.02%), C16:0 (17.02 +/- 0.09%), C18:2n-6 (14.63 +/- 0.02%), and C12:0 (15.19%) fatty acid composition. The fatty acid profile of the C-fed BSFP was characterised by high levels of C14:0 (28.16 +/- 0.11%), C12:0 (25.79 +/- 0.09%), and C18:1n-9 (13.41 +/- 0.03%), whereas FV-fed BSFP was characterised by high levels of C16:0 (19.33 +/- 0.08%), C12:0 (16.64 +/- 0.18%), and C18:1n-9 (12.51 +/- 0.04%). Our results demonstrated that chicken waste meal, fruit & vegetables waste, and their mixture can be used to feed BSFP for sustainable production. However, M-fed BSFP could be used to partially substitute fish meal in carnivorous fish feeds for having a substantially greater nutritional value than BSFP reared on other wastes and for its similarity to fish meal in terms of amino acid content

To what extent does temperature affect sex ratio ın red cherry shrimp, neocaridina davıdı? The scenario global warming to offspring sex ratio

WOS: 000419539700073An invasive freshwater shrimp, Red Cherry Shrimp (Decapoda: Caridea: Atyidae), is naturally distributed in fresh water habitats of Asia. This forage species has an important role in aquatic ecosystems by transferring planktonic production into higher trophic levels mainly including fish and aquatic animals. However, temperature strongly affects sex ratio and in turn offspring quantity. in order to determine the effect of temperature on incubation period, egg yield, offspring sex ratio as well as survival, a comprehensive experiment was conducted at three temperatures (20, 23 and 26 degrees C). Significant differences among temperatures for hatching period were an expected result. Higher survival and more eggs were achieved at 26 degrees C comparing the lower experimental temperatures. the female/male ratio, which was 80% at 20 degrees C and approximately 50% at 23 degrees C, drastically dropped to 18% at 26 degrees C. This ratio may drop to 0% at higher temperatures, which are tolerance limits for Red Cherry Shrimp. Therefore, in sex-dependent selective breeding, the temperature should be taken into consideration. Consequently, as temperature increases the sex ratio of the offspring increases in favour of the male. the continuation of global warming and rising above 26 degrees C may be an important source of stress on the natural sustainability of Red Cherry Shrimp stocks.Scientific Research Fundation of Izmir Katip Celebi University [2014-TYL-SUUF-0023]This study was supported by the Scientific Research Fundation of Izmir Katip Celebi University, Project Number: 2014-TYL-SUUF-0023

The effect of genetic polymorphisms TLR2 and TLR4 in Turkish patients with coronary artery disease

Coronary artery disease (CAD), being a multifactorial disease process, has been suggested to be associated by the interaction of both environmental and genetic risk factors. Toll-like receptors (TLRs) are related to the receptors of the innate immune system which serves as the recognition of the conserved pathogen motifs and the activation of the signals that stimulate inflammatory genes. In this study, we investigated the relationship between the polymorphisms in the TLR2-Arg753Gly, TLR4-Asp299Gly and gene and CAD. The study population consisted of 300 patients (149 men, 151 women) with angiographically documented CAD. The polymorphisms were genotyped by real time PCR. No association between TLR2-Arg677Trp or TLR4-Asp299Gly and -Thr39911e gene polymorphisms and the presence or the severity of CAD was observed. On the other hand, the TLR2-Arg753Arg genotype seemed to have a protective effect against development of CAD (OR = 0.17; 95% Cl = 0.04-0.83). Our findings suggest that TLR2-Arg753Gly polymorphism is associated with CAD susceptibility in Turkish patients. (C) 2014 Elsevier B.V. All rights reserve

Institutionalization of History in the Ottoman Empire

This article examines the process within which history was institutionalized in the Ottoman Empire. Institutional space for history had begun to be constructed within the context of interstate rivalry during the mid-nineteenth century. History had the task of "proving" the fact that the Turks had been from the very beginning a part of the "Western civilization." The essential period for the institutionalization history was that of the regime of the Committee of Union and Progress in 1908-18, providing historians to emphasize the role of the "people" in history along with large structures of geography and "civilizations." Once professional institutions were established and various history journals began to be published in this context, historians also began to pay due attention to the professional standards of the discipline. Despite the exclusionary tendencies of the Turkish official history, institutionalization during a revolutionary period functioned as a significant counter-tendency as institutions are path-dependent

Acute renal infarction in Turkey: a review of 121 cases

Kurultak, Ilhan (Trakya author)PurposeRenal infarction is a clinical condition which is caused by renal artery occlusion and leads to permanent renal parenchymal damage. In the literature, there are generally case reports on this subject, and few studies that include a large group of patients. Therefore, we aimed to present the data of a large group of patients who were diagnosed with acute renal infarction in our country in this retrospective study.MethodsThe data of patients who were diagnosed with acute renal infarction according to clinical and radiological findings in Turkey in the last 3years were examined. For this purpose, we contacted with more than 40 centers in 7 regions and obtained support from clinically responsible persons. Demographic data of patients, laboratory data at the time of diagnosis, tests performed for etiologic evaluation, given medications, and patients' clinical status during follow-up were obtained from databases and statistical analysis was performed.ResultsOne-hundred and twenty-one patients were included in the study. The mean age was 531.4 (19-91) years. Seventy-one (58.7%) patients were male, 18 (14.9%) had diabetes, 53 (43.8%) had hypertension, 36 (30%) had atrial fibrillation (AF), and 6 had a history of lupus+antiphospholipid syndrome (APS). Forty-five patients had right renal infarction, 50 patients had left renal infarction, and 26 (21.5%) patients had bilateral renal infarction. The examinations for the ethiologies revealed that, 36 patients had thromboemboli due to atrial fibrillation, 10 patients had genetic anomalies leading to thrombosis, 9 patients had trauma, 6 patients had lupus+APS, 2 patients had hematologic diseases, and 1 patient had a substance abuse problem. Fifty-seven (57%) patients had unknown. The mean follow-up period was 14 +/- 2months. The mean creatinine and glomerular filtration rate (GFR) values at 3months were found to be 1.65 +/- 0.16mg/dl and 62 +/- 3ml/min, respectively. The final mean creatinine and GFR values were found to be 1.69 +/- 0.16mg/dl and 62 +/- 3ml/min, respectively.Conclusions Our study is the second largest series published on renal infarction in the literature. More detailed studies are needed to determine the etiological causes of acute renal infarction occurring in patients

Pregnancy and its outcomes in hemodialysis patients in Turkey

Background/aim: This study aimed to investigate pregnancy frequency and evaluate the factors affecting live births in hemodialysis (HD) patients. Materials and methods: Female HD patients whose pregnancy was retrospectively reported between January 1, 2014, and December 31, 2019. The duration of HD, primary disease, and the information on whether the pregnancy resulted in abortion, stillbirth, or live birth, whether the HD duration was prolonged after diagnosing the pregnancy and whether it accompanied preeclampsia were recorded. Results: In this study, we reached 9038 HD female patients' data in the study. A total of 235 pregnancies were detected in 145 patients. The mean age was 35.42 (35 +/- 7.4) years. The mean age at first gestation was 30.8 +/- 6.5 years. The average birth week was 32 (28 -36) weeks. A total of 53.8% (no = 78) of the patients had live birth, 51.7% (no = 70) had at least one abortion in the first 20 weeks, and 13.1% (no = 19) had at least one stillbirth after 20 weeks. The rate of patients' increased numbers of dialysis sessions during pregnancy was 71.7%. The abortion rate was 22.4% in those with increased HD sessions, whereas 79.3% in those not increased HD sessions (p < 0.001). Live birth frequency was 67.2% in the increased HD sessions group and 3.4% in those who did not differ in HD sessions (p < 0.001). Conclusion: For the first time, we reported pregnancy outcomes in HD female patients, covering all regions of Turkey. It has been observed that; increasing the number of HD sessions in dialysis patients will decrease fetal and maternal complications and increase live birth rates
